Naracoorte is a small town in the south-east of the state of South Australia. It is about four hours drive from Adelaide, so more of an overnight stay than a day-trip, if being attempted with children.
Naracoorte was one of my favourite holiday places as a child – and more specifically, the Naracoorte Caves. These massive caves are naturally formed from the actions of water on limestone, and as well as featuring spectacular stalagmites (from the ground up), stalactites (from the ceiling down) helicotites (sideways!), columns and curtains (as they sound), they also feature fossils from prehistoric animals.
While there are no massive dinosaurs here, there are a large number of smaller fossils ranging from lizards and small rodents up to megafauna – giant prehistoric kangaroos and wombats, and my favourite, thylacaleo carnifex – the marsupial lion. The caves are still under excavation by archeologists so who knows what other animals will be found in the tonnes and tonnes of material yet to be sifted through.
The underground caves have guided tours while a few caves which have larger openings to the surface are self-guide. One of the caves is now home to a large colony of bats.
The rate of petrification in these caves is much (much) slower than the caves we visited in France, where the rate of water flow and the calcium load in the water was such that they could use it to petrify objects for the tourist trade. Here the stalactites, stalagmites etc grow at a miniscule rate.
